. the provision of a useful construction by Referring to the drawings, and particuwhich hitherto interdependent operations are larly to Fig. 1,.th1e reference character 10 carried on independently, to the end that a designates generally a proportioning plant break-down in one operation need not interw e ein materials, such as aggregate, from rupt the progress of the work under construcbatch boxes 11 and 12 are suitably proportion. A further object is the provision of tioned and delivered through a discharge 25 apparatus for handling and/or transporting spo t 1 dj e l' the P D g pl nt the construction materials treated in the 10, I arrange a suitable track 14 with which various operations. by which the said operacooperates a movable trolley 15 from which tions may be carried on independently of each depends a carrying hook 1 I other. A further object is the provision of A container hereinafter referred to as a 39 an improved article in the nature of a conbatch bag, and designated as at 20, is pro-.

A further object is the ing apparatus 10 so that the delivering spout provision of a material container of the above 13 enters the batch bag through a suitable 8 character which may be readily filled, opening24, and the proportioned materials handled, and dumped. and in which materials are consequently delivered into the bag.

When following analysis of the in'ventioin'it being needed, bag may be moved or picked up understood, however, that various changes by a derrick or equivalent means diagranimay be made therein by those skilled in the matically Shown as at 31 and moved to a position above the mixing plant 30. When the bag is dumped, the proportioned materials discharged from the bag fall into the mixer 30. lVhen empty the ha is released from the derrick hook by suitable trip mechanism 33 and dropped on a truck and thereupon hauled back to the proportioning plant to be filled again.

It is generally desirable to store a plurality of the filled bags adjacent the mixing plant 30. Such arrangement is advantageous in storing up materials so that the mixer may continue in operation in case of a break-down in the proportioning or hauling operations.

Referring to Figs. 3, t and 5 wherein the construction details of the batch bag are illustrated. the bag 20 is eonstitined by a heavy fabric cylinder or tube. preferably of canvas of a strength depending on the weight of the materials to be carried. For extra heavy weights, the canvas cylinder may be reinforced with ropes or rope webbing.

Disposed intermediate the ends of. the cylinder is the opening; above referred to. which is provided with an interior flap 35 shaped somewhat like the trustuni of a cone.

The materials from the proportioning; plant are thus fed through the flap 35 which functions, upon withdra of the spent 13. to prevent the materials contained within the bag from escaping when the bags are dumped on and otf the hauling trucks.

The fabric cylinder is gathered to form a closure adjacent both ends by tie ropes 36. the said ropes being attached to the bags by securing the same about bolts 3'? (Fig. pasing' through the has: fabric and protected 22.; by steel washers 38 which are preferably disposed on both the inside and outer surface of the fabric. A large. heavy canvas belt washer 4.0 is disposed between the ban fabric and the outer steel washer 38. the end of the rope being wound between the said washer 4.10 and bag fabric for securing the same when the bag is closed.

Neck bloc {S 42. which n 1? he of wood. are provided. one for each end of the has. the said blocks having central portion of reduced diameter and end portions M greater diameter. All corners of the ar preferably round d. wheres-y wear of the fabric is lessened. Each block is centrally bored as at 4t for the reception of a rooe or cable bent and secured to form the eyes 21. aforesa d and the ins de eyes or looos 21a, 22a. By reference to Fig. it will be seen that the fabric gathered about the hloclrs 4:2 with the tying ropes seating; in the annular snace about the reduced nortion 43 of said blocks: couseonentlv .he fabric is socurely joine to the bloclz til ositivelv r leased therefrom by untyinc' the rones 36.

By ref nee to Fig. it will be seen that 'he neck blocks which, when the bag; is in lobed or tied relation. engage against t gathered neck of the bag, and that the li" stresses are transmitted tln'ougrhout t1.

It will be IUQPI'GQiZLtQtl that other quivameans inieht be substituted for 2 'or tying the ban; and for sugpoiti from the holding ropes, and all such arrangements are included with- )e of the present invention. It wii be see that the severe-l obje ts of the invention are achieved and oil or advantageous results attained. [is man: changes could be made in carrying;- out the above invention. without departing from the scope thereof. itis intended that all n it ter contained in the above description shall re interpreted as illustrative and not in a uniting sense.
